A friend came to me asking if I could help him making crawling through his thousands of camera images a little easier. His camera named his pictures in a confusing manner I guess so I came up with this. This uses the EXIF data of the images to rename your images in a date/time format. It also supports sequences, which are pictures taken in rapid succession. This only does png/jpg's and the extension..
It's about to get math-y up in here. This finds which number produces the most terms in the Collatz sequence, up to a value you specify. For those who don't know, the iterative sequence in the Collatz sequence is: If n is odd: Multiply by three and add one. If n is even: Divide by two. (n*3+1)or(n/2); Continue until you end up at one. It's believed every number will eventually end up at one.
